PAPER CUTTER.

Application filed May 25,

of the cutting knife and the roll, so that the strip withdrawn may be truly and effectively out along the desired line.

The invention consists essentially of a pivotally mounted cover co-acting with a pivotally mounted knife, between which parts the paper is adapted to be drawn from the roll, as will be more fully described in the following specification, in which Fig. 1 is a transverse sectional view of the invention.

Fig. 2 is a perspective view of a modified cover. 7

In the drawings like characters of reference indicate corresponding parts in each figure.

' The numeral 1 indicates a roll of paper mounted on a shaft 2 journalled between suitable bearings. The numeral 3 indicates a casing which is adapted to be suspended from a wall 4 or other support. While I have shown the paper roll journalled within a casing, it will be obvious that such roll may be supported in a paper rack, such as is commonly used in retail stores. or in any other manner, without departing from the spirit of the invention.

The numeral 5 indicates a hinge rod extending longitudinally of the casing 3 which is preferably embedded, for the major portion of its length, in one end of thestrip of metal forming the casing. The numeral 6 indicates a'knife having a straight or serrated cutting edge 7, and which is provided at its opposite extremities with turned up ends 8, the rear edges of which are pivotally connected to the hinge rod 5 in a plane somewhat above the knife 6. The upper edges of the ends 8 of the knife are turned over and inwards as at 9 to define a pair of grooves 10 between them and the knife. V I

The numeral 11 indicates a cover for the casing which; is hingedly connected thereto as at 12 and is provided at its free 1926. Serial No. 111,644.

with a rod 13 extending longitudinally thereof, the ends of which are adapted to engage the grooves 10. of the knife ends 8 and to beslidable therealong.

lVhenthe paper roll is not enclosed with.- ina casing I may prefer to use a skeleton cover, as shown in Figure 2, in which a hingedly mounted cover strip 14, having a rod 15 along its front edge, is adapted to bear upon the strip of paper as it is led from the roll and across the knife.

Having thus described the several parts of my invention 1 will now briefly explain its operation.

The paper roll 1 is journalled between its supports, the outer edge of the knife 6'is raised as indicated by dotted lines'in Figure 1, which action causes the rod 13 to slide forwardly along the grooves 10 in the knife ends 8, and the cover 11 to be raised above the rod 5 of the casing. The free end of the paper strip, forming the roll is then passed between the rod 5 of the casing 3 and the rod 13 of the cover 11 and is drawn to the Outer edge of the knife 6. This disposes the paper in position for use as required. lVhen ,a length of paper is wanted, its free end is drawn upwards as indicated in dotted line, thus causing the cover to be lifted so that the paper can be freely drawn from the roll and as the desiredlength is reachedthe free end of the strip is lowered to a positio'n'below the level of the knife 6, thus bringing the knife into a substantially hori-. zontal-position and drawing thecover downwards into gripping engagement with that transverse line of the paper which is bearing upon the rod 5 of the casing.

From the construction shown it will be clearly seen that the grip exerted upon the paper is dependent upon the effort required to cut the paper upon the knife, so that the device can be used for cutting a light tissue or a heavy kraft paper without variation of parts.

hat I claim as my invention is:

1. A device of the character described comprising a paper support presenting stationary and movable clamping elements between which the paper is passed as it is drawn from the support, a cutter pivoted to said support and means slidably connecting the movable clamping element to the cutter in such manner as to separate the clamping 2 elements on movement of one direct on and to bring said clamping (as:

ments into clamping relation on reverse movement of the cutter.

2. A device of the character described comprising a per support presenting a stationary clamping: clement and a movable clamping element between which the paper is passed as it is drawn from the support, avv cutter pivoted to said supportin proximity to the etationary clamping member and pro riding a surface over which the paper passes: from the said chnnping lnemhersn said cutter being equipped with a pair of groome and projections carried by the movable clamp ing member and engaging in said grooves, the location of the grooves and projections with reference to the pivot point of the cutter being such as to cauae the movable clanibing memberto recoci "frtnnjor to up proach the stationary clampm inember upon swinging movement of the cutter.

3. A device of the characterdescribed comprising a container equipped with a hinged cover aflording a movable clamping elementaflapted to cooperate with a stationarj. clamping elenient afi'orded by a wall portion of the cmltainerk a cutter hinged to said container and a means connecting the cutter and the cover wher the latter is movable to and from the stationary clamp: ing member in dircotreepohe to swinging movement or the cutter.
